How to find the values in a flex rule

I am trying to figure out how to select all the values in a fnd flex rule.  For example, for the account string co-loc-prod-dept-acct, all values are varchar.  The acct segment has a security rule which limits the account# let's say AP is allowed to use.  I need to find all the account numbers AP is allowed to use.

So if the security rule is defined as Include 0000-zzzz, Exclude the ranges 1001-1200 and 3900-3900.  I would need to list the account # that are not in the exclude ranges.  Can someone point me in the right direction?

Thanks!
